2)REGISTERS :
*************
- There are five registers all of which have special uses.
- Each register is 24 bits in length.

   Mnemonic    Special use
   ********    ***********
      A        Accumulator; used for arithmetic operations.
      X        Index register; used for addressing.
      L        Linkage register; The JSUB (Jump to subroutine) stores                  the return address in this register.
      PC       Program counter; contains the address of next                           instruction to be fetched for execution.
      SW       Status word; contains a variety of information ,                        including a condition code(CC).

3)DATA FORMATS:
***************
- Integers are stored as 24-bit binary numbers.
- 2’s complement method is used for negative values.
- Characters are stored using their 8-bit ASCII codes.
- There is no floating point hardware on SIC.

4)INSTRUCTION FORMATS:
**********************
- All machine instructions on the standard version of SIC have the following 24-bit  format.

         8           1          15
    —————————————————
   |   opcode      | x|       address                  |
    —————————————————

- The flag bit ‘x’ is used to indicate indexed addressing mode.

5)ADDRESSING MODES:
*******************
- The target address is calculated from the address given in the   instruction as follows.

   Mode             Indication           Target address calculation
   ****************************************************************
   Direct           x=0                  TA = address
   Indexed          x=1                  TA = address + (X)
   [   (X) represents the contents of register X  ]

6)INSTRUCTION SET:
******************
CLICK THIS LINK TO SEE THE COMPLETE LIST OF INSTRUCTION SET OF SIC

7)INPUT AND OUTPUT:
*******************
- The following are previlized instructions that perform I/O i.e. they are under the control of OPERATING SYSTEM and not in controlled by user program.

- Test Device (TD) instruction sets the condition code (CC) to indicate the result of the test.A setting of < means the device is ready to send or receive a byte of data ,  and =  means the device is not ready.

- Read Device (RD) and Write Device (WR) transfer a byte of data from and to the device specified in the address field.

1)INSTRUCTIONS THAT LOAD THE REGISTERS
**************************************
LDA m 00 A <- (m..m+2)
LDCH m 50 A[Right most byte] <- m
LDX m 08 L <- (m..m+2)
LDL m 04 X <- (m..m+2)

2)INSTRUCTIONS THAT STORE THE REGISTER VALUES
*********************************************
STA m 0C m..m+2 <- (A)
STCH m 54 m <- (A)[Right most byte]
STX m 14 m..m+2 <- (X)
STL m 10 m..m+2 <- (L)

3)INTEGER ARITHMETIC OPERATIONS
*******************************
ADD m 18 A <- (A) + (m..m+2)
SUB m 1c A <- (A) – (m..m+2)
MUL m 20 A <- (A) * (m..m+2)
DIV m 24 A <- (A) / (m..m+2)
AND m 40 A <- (A) & (m..m+2)
OR m 44 A <- (A) | (m..m+2)

4)COMPARISION INSTRUCTION
*************************
COMP m 28 (A) : (m..m+2)
(Condition code CC is set to = or < or > to indicate the result)

5)CONDITIONAL JUMP INSTRUCTIONS
*******************************
J m 3C PC <- m
JEQ m 30 PC <- m if CC is set to =
JGT m 34 PC <- m if CC is set to >
JLT m 38 PC <- m if CC is set to <
JSUB m 48 L <- PC ,PC <- m
RSUB m 4c PC <- (L)

6)INSTRUCTIONS THAT PERFORM I/O
*******************************

TD m E0 Test device specified by (m)

RD m D8 (A) [Right most byte] <-
Device specified by (m)

WR m DC Device specified by (m)<-
(A) [Right most byte]

Ans : A transient variable is a variable that may not be serialized. .     2.Which containers use a border Layout as their default layout?     Ans : The window, Frame and Dialog classes use a border layout as their  default layout..     3.Why do threads block on I/O ?     Ans : Threads block on i/o (that is enters the waiting state) so that other  threads may execute while the i/o Operation is performed..     4. How are Observer and Observable used ?     Ans : Objects that subclass the Observable class maintain a list of observers.  When an Observable object is updated it invokes the update() method of each of  its observers to notify the observers that it has changed state. The Observer  interface is implemented by objects that observe Observable objects..     5.What is synchronization and why is it important ?     Ans : With respect to multithreading, synchronization is the capability to  control the access of multiple threads to shared resources. Without  synchronization, it is possible for one thread to modify a shared object  while another thread is in the process of using or updating that object's value.  This often leads to significant errors..     6.Can a lock be acquired on a class ?     Ans : Yes, a lock can be acquired on a class. This lock is acquired on the  class's Class object...     7.What's new with the stop(), suspend() and resume() methods in JDK 1.2?

Ans :The digits 0 through 9 may not be used as the first character of an  identifier but they may be used after the first character of an identifier..     15.What is the List interface?     Ans : The List interface provides support for ordered collections of objects..     16.How does Java handle integer overflows and underflows?     Ans :It uses those low order bytes of the result that can fit into the size of  the type allowed by the operation..     17.What is the Vector class?     Ans : The Vector class provides the capability to implement a growable array  of objects.     18.What modifiers may be used with an inner class that is a member of an outer  class?     Ans : A (non-local) inner class may be declared as public, protected, private,  static, final, or abstract..     19.What is an Iterator interface?     Ans : The Iterator interface is used to step through the elements of a Collection..     20.What is the difference between the >> and >>> operators?     Ans : The >> operator carries the sign bit when shifting right. The >>> zero-fills  bits that have been shifted out..     21.Which method of the Component class is used to set the position and size of  a component?     Ans : setBounds().        22.How many bits are used to represent Unicode, ASCII, UTF-16, and UTF-8 characters?     Ans : Unicode requires 16 bits and ASCII require 7 bits. Although the ASCII  character set uses only 7 bits, it is usually represented as 8 bits. UTF-8  represents characters using 8, 16, and 18 bit patterns. UTF-16 uses 16-bit  and larger bit patterns..     23.What is the difference between yielding and sleeping?     Ans : When a task invokes its yield() method, it returns to the ready state.  When a task invokes its sleep() method, it returns to the waiting state..     24.Which java.util classes and interfaces support event handling?     Ans : The EventObject class and the EventListener interface support event  processing.     25.Is sizeof a keyword?     Ans : The sizeof operator is not a keyword..     26.What are wrapped classes?     Ans : Wrapped classes are classes that allow primitive types to be accessed  as objects..     27.Does garbage collection guarantee that a program will not run out of memory?     Ans : Garbage collection does not guarantee that a program will not run out of  memory. It is possible for programs to use up memory resources faster than they  are garbage collected.It is also possible for programs to create objects that  are not subject to garbage collection.     28.What restrictions are placed on the location of a package statement within  a source code file?     Ans : A package statement must appear as the first line in a source code  file (excluding blank lines and comments)..     29.Can an object's finalize() method be invoked while it is reachable?     Ans : An object's finalize() method cannot be invoked by the garbage  collector while the object is still reachable. However, an object's finalize()  method may be invoked by other objects..     30.What is the immediate superclass of the Applet class?     Ans : Panel.     31.What is the difference between preemptive scheduling and time slicing?     Ans : Under preemptive scheduling, the highest priority task executes until  it enters the waiting or dead states or a higher priority task comes into existence.  Under time slicing, a task executes for a predefined slice of time and then reenters  the pool of ready tasks. The scheduler then determines which task should execute  next, based on priority and other factors..        32.Name three Component subclasses that support painting.     Ans : The Canvas, Frame, Panel, and Applet classes support painting        33.What value does readLine() return when it has reached the end of a file?

Ans : A task's priority is an integer value that identifies the relative order  in which it should be executed with respect to other tasks. The scheduler attempts  to schedule higher priority tasks before lower priority tasks..     44.What class is the top of the AWT event hierarchy?
